The local oscillator level at TP1 is 1.06 VDC  (0.8 - 1.2)
LNA at TP2 is 241 mV with R13 set at its limit (CW)
R22 at its limit (CW) will just hit 20 W (PEP)

L15 peaks at 2 turns above the top of the can instead of two turns
down.  I'm suspicious that I may have the wrong capacitor at C53.  The
C53 is suppose to be 18pf.  The only capacitor in the kit that has 18
anywhere on it is a huge (relatively speaking) triangular shaped
capacitor that has three lines of text.

The top line reads 18J
The second line reads 1KV
The third line reads 33

I could find no other capacitor that reads 18 or 180 with the kit.
Nor could I find any capacitor that should read 33.  So I assumed that
this must be the right capacitor for C53, a substitute perhaps, but it
should work.

The way L15 peaked at 2 turns above the can, though raises some
concern.

I lack the know how to determine if everything is as it should be.
